+access to an input device and maintaining a model of the keys that are
+pressed.  It then applies your remapping configuration to produce the
+effective set of pressed keys and emits appropriate changes to a virtual
+output device.
+
+Its remapping is effective system-wide: in Wayland, X11 and the Linux
+console.")
